Yes, it should break eventually. Not sure about cycles though... I think humans have a tendency to see/hallucinate cycles from random variation. This one might be done, however. I suspect that February 2010 storm may have been our last best chance of breaking this one; however, despite over 20" of snow, it was split fairly evenly over two days, keeping the calendar day total under one foot. Definitely can see each period getting longer... records began in 1880, first streak ends in 1884, then 1890, then 1901, then 1902, then 1913, then a long break ending in 1942, then 1950, then 1960, then 1966, another long break ending in 1993 (Storm of the Century) and none thereafter. If it is the last calendar day with one foot of snow in Pittsburgh history, fitting for it to be the March 1993 Superstorm.

The default setting is no missing days, so it treats any missing date as ending the streak. You have to allow some number of missing days to avoid that.

Incredible stuff, with NHEM anomalies pushing up towards 2C above the 1981-2010 mean as we head towards the end of the month. This has been one heck of a hemispheric heat wave over the last month or so.

Record warmth prevailed across Minnesota yesterday, with record highs of 56F at Minneapolis-St. Paul and 55F at St. Cloud. Fargo reached an incredible 60F, setting a daily record and making yesterday the 3rd latest date in the calendar year on which that temperature milestone was reached or exceeded.

If not for that piddly 0.2" on April 9, we'd be near our longest stretch without measurable snow on record right now, as that was the only measurable snow after March 8.

Even better elsewhere, back when there were more official snowfall observations. Morgantown came in with nearly a foot. Northern Pennsylvania got clobbered. The daily reported snowfall on the 11th appears to have been so high at DuBois, it got automatically rejected by the automated rejection feature for suspect readings in xMacis. A review of the daily snowfalls and change in depth suggests over 2 feet fell, with depths peaking at 34" from the 12th through 14th. Bradford had a peak depth of 39 inches.

Certainly, a great way to break a snowfall drought with nearly 10" of snow at the airport (looks like there may have been some mixing?).

I didn't say anything about a torch. Just asked a question as bluewave's map of the Euro weekly showed +1 to +3C across the East this week (11/24 to 12/1).

Interesting look here. 10 warmest Novembers, minus 2009-2010 (significant ENSO mismatch) and 1913-1914 (age). Rather similar to CPC's outlook, except they are a bit more robust with the cold extension to the southeast.

The current three warmest Novembers are 1999 (+5.14F), 2016 (+4.98F), and 2001 (+4.42F). 2025 looks like it will be in the mix with these years. Rolling the 3 warmest Novembers forward through meteorological winter, here's what that analog map looks like. 1999-2000 is 3rd warmest of all time, 2016-2017 is 9th warmest, and 2001-2002 is 10th warmest.

I thought there was supposed to be a big cold snap around Thanksgiving?

Looking specifically at Erie, the low end GLERL projection would bring lake levels down to 173.78 meters by late winter, which has only been reached or exceeded twice since the mid 1960s on a monthly average - 173.78m in March 2003 & 173.75m in February 2011. That's going with the low-end projection, so it might not happen, but certainly a stark contrast from the near record high levels of 2019 & 2020.

Do you think the atmosphere is still capable of producing 4" of snow in a single day at locations like New York and Pittsburgh (see below)? I noticed Pittsburgh has obliterated its longest stretch without 4" of snow, and this includes data from the downtown station that was a few hundred feet lower in elevation with a seasonal snowfall average of about ~12 inches less than the airport. So this is completely unprecedented since at least the 1870s. I have to wonder if the 40N parallel is simply too for south to see such heavy snow with the current atmospheric conditions? Maybe NYC will fare a little better being on the coast?

It's been an incredible 1,348 days since the last calendar day with 4" of snow. You have to think eventually that breaks, or do you guys think it is no longer possible to see 4" of snow in a single day at PIT?
